Nina Lee,
If you had a hydraulic floor jack, two jack-stands, correct 1/2" metric sockets, 1/2" drive - 12" long ratchet, synthetic brake grease for the slider pins, factory Toyota brake pads and pad shims this job is a 0. Not a1, 2, 6 or 8 this job is a ZERO.
You an I would have her done in an hour! I'm a bit puzzled though. How many miles do you have on your Toyota? The original brakes should a bare minimum of 50,000 miles unless you live in a city, do all city driving and drive like Chub Frank or Josh "Kid" Richards. Look up either of these guys and see if you go around corners like they do!
